Claude
Anthropic's Claude — long-context, careful, great at writing and code.
Claude reviews and recipes: Sonnet vs Opus, when long context wins, Projects, Artifacts, and Claude Code workflows.
Claude is the model we reach for when the input is long, the writing has to be good, or the code needs to be reviewed as much as written. Anthropic's flagship trades a little breadth for careful reasoning and a genuinely useful long-context window — and that changes how you use it.
This hub covers the practical stuff: Sonnet vs Opus for real jobs (not benchmarks), Projects for persistent context, Artifacts for one-shot mini-apps, Claude Code for terminal work, and Computer Use for agentic browser tasks. We also cover what Claude is bad at, so you don't fight the tool.
If you're deciding between Claude and ChatGPT, jump to our head-to-head. If you're already on Claude and want to get more out of it, start with the prompt patterns and the Projects walkthrough.

Frequently asked about Claude
›Sonnet or Opus — which should I use?
Sonnet is the daily driver: fast, capable, cheaper. Opus is worth it when the task rewards deeper reasoning — long-form writing, careful code review, complex research. Don't default to Opus; you'll usually pay more for the same answer.
›When does Claude beat ChatGPT?
Long documents, careful writing that needs voice, and code review where you want reasoning about intent — not just autocomplete. ChatGPT still wins for broad tool use, image generation, and the largest ecosystem of integrations.
›What are Claude Projects actually for?
Projects let you attach files and a persistent system prompt so every chat in that project starts with the same context. Use them for anything you revisit: a codebase, a client, a book, a research area.
›Is Claude safe to use with sensitive documents?
